Abstract: With the development of nuclear technology, plutonium has gradually become the main nuclides in the nuclear fuel system, and the number of people engaged in plutonium operations has increased year on year. However, the health effects of plutonium need to be further determined. Some nuclear powers in the world have conducted some epidemiological studies on the health effects of workers exposed to plutonium. The research results are different for plutonium workers in different facilities. The Mayak workers had a relatively high dose of internal radiation exposure, and the cohort studies had sufficient statistical capacity. However, the cohort study of low-level plutonium radiation exposure in the United States and the United Kingdom had not determined the dose-effect relationship. The reliability of epidemiological studies for plutonium workers depends on the accuracy of internal organ dose assessment. There is still a certain gap between China and other major nuclear powers in the world about the research on the health effects of plutonium workers. It is expected to provide research ideas for the long-term health effects of the plutonium workers in China through this review.
